Abstract
The present invention discloses an absorbent article, such as a diaper, containing cuffs with a skin care composition disposed thereon. The skin care composition disposed on the cuffs is transferable to the wearer's skin by normal contact and/or wearer motion and/or body heat. The cuffs are at least partially assembled using an oil resistant adhesive that is both material friendly and process friendly.
Description
Technical field
The present invention relates to comprise the closing in absorbent device of (comprising that elastic leg closes up), such as diaper, training pants, adult-incontinence articles, sanitary towel, women's medicated clothing etc.More particularly, on the present invention relates to close up or closing in and top flat be provided with the absorbent device of skin care compositions and the device of this absorbent device of assembling, skin care compositions can be transferred on the wearers skin by normal contact and/or wearer motion and/or body heat, and the device of assembling absorbent device can be resisted the oil composition of skin care compositions.
Background technology
Major function as absorbent devices such as disposable diaper and incontinent brief or medicated clothings is absorption and holds bodily exudate.This articles for use are designed for clothes or other article that prevent that bodily exudate from making dirty, getting wet or pollution contacts with the wearer, such as sheet.When bodily exudate when the slot leakage between articles for use and wearer's shank or the waist is to adjacent medicated clothing the common failure conditions of this series products takes place, thereby the leakage of bodily exudate is in time not to be absorbed in articles for use and absorbent device can not be kept good suitability on one's body the wearer and forms the slit that the ejection that is leaks and cause owing to bodily exudate.
For example, urine trends towards being deposited on the top flat in the mode of shoving, thereby makes urine move to slit between articles for use and the wearer, contacts with medicated clothing or other article and is absorbed by these article in this place, slit urine.In addition, be not easy to be floated on the body contacting surface by the lax feces that absorbent device absorbs and pass articles for use and the slit of wearer's shank or waist.
Present disposable diaper has one or more closing ins (being generally elasticity closes up) of top flat, egative film, absorbent article core, contact wearer shank and/or waist.These elasticity close up and can prevent effectively that liquid is from the diaper wicking of full of liquid or cross on the medicated clothing that flows to the diaper EDGE CONTACT; wherein elasticity closes up as the obstacle between diaper edge and the contact medicated clothing, and also provides usually around the sealing function of wearer's shank or waist to keep around the sealing of shank or waist and the slit is minimized.Yet the power that produces owing to elastic component causes higher local pressure along very narrow regional centralized, and this elasticity closes up and has the trend of increase for form impression on wearers skin.Because even baby and old incontinent person's skin are fragile and all very sensitive to very slight pressure or friction, so above-mentioned influence to skin is for the product especially severe by baby and old incontinent individuals wear.
The skin that these skin influences cause owing to these products seals and further increases the weight of.The skin sealing that diaper causes can cause excessive hydration potentially.Therefore, excessively easier being subjected to of the skin of hydration contacts the infringement that causes friction by normal wearer's motion with closing up with elastic leg.Excessively the easier dermatosis that gets of the skin of hydration comprises diaper rash, erythema, heat rash, wearing and tearing, impression and the loss of skin protection layer.The protection effectiveness reduction of wearing and tearing, excessive hydration skin can further cause increasing the weight of of diaper rash.(following definition has been done in 333.503 pairs of diaper rashs of 21CFR §: by the one or more chafings that (perineum, buttocks, lower trunk and femoribus internus) causes in the diaper zone in the following factors: moisture, sealing, friction, with urine or sealing or both Continuous Contact, machinery or chemical stimulation.)
In order to solve the dermatosis problem relevant with other absorbent device with wearing diaper; absorbent device is placed the wearer on one's body before, care-giver or wearer often apply for skin to shank, external genital and/or other position has protectiveness and/or curative articles for use.This process generally includes: the care-giver wipes articles for use on the wearers skin then to the articles for use that oneself apply protection skin on hand.In order to eliminate this waste, dirt, the consuming time and process easily forgotten, people are attempting preparation contains the skin protection material on the articles for use top flat absorbent device.
Prior art also is devoted to weaken owing to use the influence of closing up skin being produced, and promptly improves the beneficial effect of skin protection by the absorbent device that skin care compositions is set on closing up, and particularly in use provides beneficial effect on the skin of the contact of closing up.This skin care compositions can be transferred on the wearers skin so that these beneficial effects to skin to be provided.The absorbent device that has the leg cuff of these skin care compositionss on useful especially skin care compositions and its is described in the U.S. Patent application No.08/962310 that submitted to people's such as Schulte name on October 31st, 1997, and this patent application is quoted as a reference herein.
Yet,, still need further improvement although these skin care compositionss and absorbent device provide the beneficial effect of many skin protections.For example, the skin care compositions function that do not suppress to close up in absorbent device is very important.Oil composition in the skin care compositions can be diffused into inner surface from the body surface that closes up, and these compositions can contact with the structural adhesive that is used to assemble closing on inner surface.If this class contact has taken place, then oil composition can make binding agent plasticising, causes that modulus wherein reduces or the cohesive strength loss.This can cause creep under stress continuously.The creep here refer to the slow surrender of binding agent or close up in elastic component slowly lax.This creep finally makes the closing in material separate with elastic component to cause the increase that reduces and leak around the contractility that closes up.
Up to above-mentioned U.S. Patent application No.08/962310, people recognize that just the closing in absorbent device applies the meaning of skin care compositions.Also just recognize the interaction of absorbent article construction binding agent between skin lotion that applies usually and ointment.
For example, one of shortcoming that applies skin care compositions to the closing in of using based on the binding agent assembling of the prior art of block copolymer chemistry (as the styrene-isoprene-phenylethene of the following SIS of being called) is the trend that elastic component has creep.
The United States Patent (USP) 6010972 of authorizing people such as Zacharias on January 4th, 2000 discloses the elastic composite body that apparatus has the binding agent assembling of required grease resistance and handling property.The viscosity that people's such as Zacharias United States Patent (USP) 6010972 discloses binding agent in the time of 275 is ideal less than about 40000 centipoises.People's such as Zacharias United States Patent (USP) 6010972 further discloses the binding agent that in the time of 275 viscosity is higher than 40000 centipoises and has been easy to cause the bonding of relatively poor binding agent and substrate.
The shortcoming of prior art comprises that requirement has enough low viscosity and makes binding agent to handle and to be applied in the substrate effectively by common treatment facility.The viscosity of binding agent is high more, handles just difficult more.But viscosity can not be hanged down to hinder and be formed effective adhesive bond.
Therefore, wish to obtain absorbent device, be included in the elastic component that keeps its integrity under the prerequisite that the oil-containing skin care compositions exists.Also wish very much to obtain under high viscosity, to handle and the bonded absorbent device of virtual viscosity.
In view of this situation of prior art, make us surprised and find unexpectedly to comprise that the absorbent device of segmented copolymer hot melt binding agent presents anti-wriggling property under the situation that skin lotion exists.In addition, also being surprised to find binding agent of the present invention can be on each element of handling and being applied to absorbent device under the viscosity higher than prior art effectively.

Although be assigned to the consumption of the skin care compositions in the closing in is an importance of the present invention, and the consumption that is delivered to the compositions on the wearer's skin between the operating period of one or more processed closing ins is even more important.Although for the consumption that provides required skin protection beneficial effect must be delivered on the skin will depend on the character of the compositions that is adopted to a certain extent, the applicant finds, can only transmit quite low consumption, still can provide required skin effects simultaneously.This is for preferred compositions, those compositionss as be shown in the examples, especially like this.
Another benefit of the present invention is using so that the required low but compositions of effective dose to be provided of control skin care compositions.This uses differently with the typical irregular craft of skin protectant, and under the sort of situation, care-giver/user will be used usually than needed big a lot of amount.Because the result on from the skin-communication to articles for use, the manual too much material that adds also may produce adverse influence to the fluid handling properties of absorbent device.Really, for some material such as vaseline, the amount of using may actually cause inaccessible effect by hand, thus infringement skin.A benefit of the present invention is to provide a barrier to surface moisture, avoids the obturation (that is, keeping skin permeability) of skin simultaneously.Therefore, the invention enables the compositions of optimised quantity to be sent on the skin to keep and/or to improve skin health.
Be delivered to the consumption of the skin care compositions on the wearer in about 3 hours during (wear the time typical daytime) for absorbent device of handling of use, particularly concerning preferred skin care compositions as described in example 1 above, preferred consumption is at least about 0.01 milligram/inch during wearing in 3 hours
2(0.0016 milligram/centimetre
2), more preferably at least about 0.05 milligram/inch
2(0.0078 milligram/centimetre
2), further preferred about 0.1 milligram/inch
2(0.016 milligram/centimetre
2) compositions be delivered on the skin.Usually, the consumption of the compositions transmitted during wearing in 3 hours of articles for use of handling is about 0.01 milligram/inch
2(0.0016 milligram/centimetre
2) to about 8 milligrams/inch
2(1.24 milligrams/centimetre
2), be more preferably about 0.05 milligram/inch
2(0.0078 milligram/centimetre
2) to about 6 milligrams/inch
2(0.93 milligram/centimetre
2), further preferably about 0.1 milligram/inch
2(0.016 milligram/centimetre
2) to about 5 milligrams/inch
2(0.78 milligram/centimetre
2).
Will be appreciated that, used multiple material in the skin care compositions that is delivered to according to the present invention on the skin, those are considered to safely and effectively that the material of skin protectant is the used inevitable material of the present invention.This class material comprises food and medicine management board of the United States Federal (FDA) about defined I class active substance in the provisional final regulation of the human skin care medicine that uses of nonprescription drugs, and it comprises at present: allantoin (alantoin), gel aluminum hydroxide, calamine cream (calamine), cupu oil, polydimethylsiloxane, cod liver oil (mixing), glycerol, Kaolin, vaseline, lanoline, mineral oil, shark liver oil, white vaseline, Talcum, local starch, zinc acetate, zinc carbonate, zinc oxide etc.Other can applicable material be a food and medicine management board of above-mentioned the United States Federal (FDA) about the III class active substance defined in the provisional final regulation of the human skin care medicine of nonprescription drugs, and it comprises at present: active yeast cell derivative, aldioxa, aluminum acetate, microporous fibre element, vitamin D
3, colloidal oatmeal powder, cysteine hydrochloride, pantothenylol, Peru balsam oil, protein hydrate, racemic methionine, sodium bicarbonate, vitamin A etc.Will be appreciated that, one or more optional material can with other composition, as described herein those are used in combination.
As mentioned below, though among the present invention used skin care compositions needn't preferably have fusing point and distribute, but on the wearer-contacting surface (health face) that makes said composition relative fixed at room temperature and be confined to close up, at least a portion compositions can be passed to wearer under body temperature, and still not exclusively is liquid under extreme storage requirement.Preferred said composition is easily transferred on the skin by normal contact, wearer motion and/or body heat.Because the preferred basic fixed of said composition is on the wearer-contacting surface that closes up, so the skin care compositions that only needs to hang down consumption is relatively given desirable skin protection benefit.In addition, among the present invention during used articles for use, need not special the obstruct or packaging material in packing.
In preferred embodiments, the used skin care compositions of the present invention 20 ℃ be under the ambient temperature for solid, be more typically semisolid." semisolid " refers to that said composition has the rheological characteristic of pseudoplastic behavior or plastic fluid.If do not apply shearing, the outward appearance of said composition can be semisolid, but improves with shear rate, and compositions becomes mobile.Although this is that it also comprises some small amount of liquid components because said composition mainly comprises solid constituent.
Preferably, the zero-shear viscosity of compositions of the present invention is about 1.0 * 10
6Centipoise is to about 1.0 * 10
8Centipoise, more preferably 5.0 * 10
6To 5.0 * 10
7Centipoise.Term used herein " zero-shear viscosity " refers under very low shear rate (for example 1.0 seconds
-1) with the viscosity of dish and cone viscosimeter mensuration; A kind of suitable instrument is from New Castle, and the TA instrument company of DE buys with the CSL100 model.Those of ordinary skill in the art will recognize that other component that can use except that high melting point component (as described below) is to provide zero-shear viscosity.The component of illustrative comprises that use clay for example known in the art or pyrogenic silica foundation have the structure of yield value.Also can be by viscosity is measured the zero-shear viscosity of the compositions that contains this class component to the zero shear rate under about 20 ℃ of temperature to the curve extrapolation of shear rate.
Preferred compositions at least at room temperature is that semisolid is so that the compositions migration is minimum.In addition, the final fusing point of compositions (100% liquid) preferably be higher than may 45 ℃ possible " harshness " storage requirement (for example, the car body of the warehouse of Arizona, Florida etc.).Particularly, preferred compositions has the fusing point distribution shown in the following table 1:
Table 1
| Characteristic preferable range most preferred range |
| Liquid percent 2-50 3-25 under room temperature (20 ℃) |
| Liquid percent 25-95 30-90 under body temperature (37 ℃) |
| Final fusing point (℃) 〉=38 〉=45 |
Owing to be solid or semisolid at ambient temperature, so the trend that preferred compositions obviously flows to and moves in undesirable zone of absorbent device can be very not big.This means only needs less skin care compositions just can give ideal treatment, protectiveness and/or conditioning beneficial effect.
In order to strengthen the stationarity of preferred compositions, the viscosity of composition prepared should be high as much as possible, thereby prevent to flow to undesirable position in the diaper from closing in.Unfortunately, in some cases, higher viscosity may composite inhibiting be delivered on the skin of wearer or may be difficult under the processing problems use not occurring.Therefore, viscosity should reach a balance, promptly the enough height of viscosity so that compositions be fixed on the surface of closing in, again can be too not high and hinder on its skin that is delivered to wearer.The suitable range of viscosities of compositions is generally about 1-5000 centipoise, preferred about 5-300 centipoise, more preferably from about the 5-100 centipoise adopts rotary viscosity measuring (a kind of suitable viscometer can be by Melrose Park, and the Lab Line instrument company of IL buys with 4537 models) down at 60 ℃.This viscometer uses No. 2 spindles (spindle) to move under 60rpm.

Be used in some skin care compositions of the present invention another optional but the component that is even more important is the reagent that compositions (comprising preferred lubricant and/or other skin condition/protection reagent) can be fixed on the interior or desired area on it of treated closing in.Because some preferred lubricant has plasticity or fluid consistency in the compositions under 20 ℃, this lubricant often will flow or move, even also be like this when being subjected to the shearing of appropriateness.When lubricant is applied on the health face of closing in or other position, when especially being in fusing or molten condition, lubricant can not keep mainly in treated zone or on it.On the contrary, this lubricant often will move and flow in the unwanted zone of absorbent device.
Specifically, if lubricant migrates into the inside of articles for use, it may produce undesirable influence to the absorbability of absorbent article core, and this is by due to the hydrophobic property of many lubricants used in the compositions that is used for the present invention and other skin conditioning agent.This also means and need use much more lubricant to obtain required beneficial effect on closing up.The consumption that increases lubricant not only increases cost, but also make to the absorbefacient adverse effect of absorbent article core and during the processing/repacking of treated closing in the unfavorable transmission of compositions aggravate.
By making lubricant mainly be fixed on the surface of the closing in that compositions will apply or in the zone, fixative has been offset lubricant migration or mobile this trend.It is believed that this part is because the fusing point that fixative is brought up to lubricant with the fusing point and/or the viscosity of compositions and/or the fact on the viscosity.Since fixative preferably miscible with lubricant (by suitable emulsifiers dissolve in lubricant or be dispersed in wherein), therefore, in the zone that it also is trapped in lubricant on the wearer-contacting surface of closing in or lubricant will apply.
Also is favourable with fixative " locking " on the wearer-contacting surface of its closing in that will apply or zone.This can be when using on being applied to closing in fast the fixative of " fix " (or curing) realize.In addition, by aerator, fan, chill roll etc. the crystallization that external refrigeration can be quickened fixative is carried out in the closing in of handling.
Except can miscible with lubricant (or being dissolved in wherein), this fixative preferably has such fusing point and distributes, promptly its will to provide be solid or semisolid compositions at ambient temperature.In this respect, the fusing point of preferred fixative is at least about 35 ℃.Like this, this fixative itself will not have migration or mobile trend.The fusing point of preferred fixative is at least about 40 ℃.Usually, the melting range of fixative is from about 50 ℃ to about 150 ℃.

The binding agent of anti-oleaginous material (oleaginous material)
General requirement
Just as discussed above, be applicable to the oily ingredient in the anti-skin care compositions discussed in this article of the material of assembling absorbent device of the present invention, the material that is confined to simultaneously within reason is selected or process flexibility.For example, be suitable for the material of making interval Flexible Connector (spacing elastic attachment member) 94 and must and stop that closing in part 63 is maintained fixed relation the maintenance of interval elastic component, even when contacting also be so (, suitable material must be oil-resisting) with oily ingredient.Suitable material also should have viscosity-hot property (visco-thermal properties) so that: 1) application temperature of material should be too not high and restriction be used to assemble absorbent device material selection (promptly, binding agent is material friendly (material friendly)), 2) the required energy of molten material should be too big and the over-drastic time of needs is (promptly before not having the low viscosity that is fit to use at material, reaching the required time of application temperature should not make us unacceptably oversize) and 3) performance should make material not produce the process reliability problem in the use of the material of fusing.
The binding agent of anti-oleaginous material comprises those disclosed in the U.S. Patent application serial number of submitting to people's such as Sheehan name on May 1st, 1,998 60/083,913, and the content that it is disclosed is introduced the present invention as a reference.The binding agent that is applicable to the preferred anti-oleaginous material among the present invention is a hotmelt as commercially available and by H.B.Fuller Company (St.Paul, Minnesota) binding agent based on block copolymer of Sheng Chaning from market with HL-1719.Hereinafter description is applicable to the standard of material of the present invention.
Grease resistance
Being applicable to the adhesive material of assembling absorbent device of the present invention, is that assembling, transportation, storage at absorbent device or the liquid that may contact this class binding agent between the operating period have resistance as a major criterion as the interval Flexible Connector 94 in the diaper 20.The liquid of illustrative comprises water, aqueous body excretions such as urine, other body excretions such as menstruation or feces, with the oily ingredient of skin care compositions, as mineral oil, vaseline, fatty ester, aliphatic alcohol, fatty acid, polysiloxane compound with may be listed in above to other materials in the description of skin care compositions of the present invention.
Although it is important that all above listed various liquid are had resistance, but providing oleaginous material in the prior art, composition in the skin care compositions of beneficial effect of desirable skin health is provided in the time of as has been found on being administered to diaper, and it is difficult especially to have the resistance aspect.The applicant has been found that the closing in of having handled with described skin care compositions above for, is very ideal less than the creep value (creep value) of about 0.35 inch (8.9mm).Particularly, when according to hereinafter when the method described in Test Methods section assessment has creep at least about the sample of 25 closing ins, the end be no more than about 10% creep value that should have greater than about 0.35 inch (8.9mm).Preferably, the end less than about 7.5% creep value that should have greater than about 0.35 inch (8.9mm), more preferably, the end less than about 5% creep value that should have greater than about 0.35 inch (8.9mm).
The table 3 of embodiment 3 has been listed and had been handled with skin care compositions and use stopping of binding agent of the present invention (that is, with the commercially available from the market oil-resisting block copolymer of HL-1719) assembling to close up 62 and had handled and used the average creep value that stops closing in 62 that polybutylene-based binding agent assembles and the creep value percentage ratio greater than the elastic cord end of about 0.35 inch (8.9mm) with skin care compositions.Embodiment 1 and 2 has described the assembling and the processing of the diaper with this class closing in.
Then according to the hereinafter creep of the assessment of the method described in Test Methods section closing in.Just as illustrated, handle and identical with the creep of the closing in of handling with skin care compositions and assembling with polybutylene-based binding agent basically with skin care compositions with the creep of the diaper of binding agent assembling of the present invention.Traditionally, when diaper was assembled with the skin care compositions processing and with not oil-resisting binding agent, creep increased basically.
The adhesive composition that comprises polybutene that discovery has grease resistance is included on May 1st, 1998 with those compositionss disclosed in U.S.'s serial number 60/083,913 of people's such as Sheehan name submission, and this document is introduced the present invention as a reference.
Have been found that the adhesive composition that comprises block copolymer such as HL-1719 has ideal especially grease resistance.This class binding agent can further comprise other polymer or copolymer, tackifying resin, wax, stabilizing agent, and other materials known in the art.This class adhesive composition also is known as hotmelt in the art.Although be not wishing to be bound by theory, think that this class grease resistance is that (weakening) is preceding can absorb big gauging because compositions is in reduction.
The material friendly
Another major criterion about the suitability of the present invention is " a material friendly ".If when using binding agent to assemble absorbent device, the use of binding agent can be to the over-drastic restriction of generation as the Available Material type of absorbent device parts, and binding agent then used herein is " material close friend ".For example, the binding agent application temperature that has been found that about 375 (191 ℃) is producing the hole as in the low quantitative film of absorbent device egative film usually.This temperature sensitivity limits the upper limit of the application temperature of suitable hotmelt effectively.
The processing friendly
Be applicable to that the binding agent among the present invention also has processing friendly (process friendly).If binding agent can not add unnecessary restriction to applying with use, then this binding agent is " processing is friendly ".The instantiation of the contribution that is brought of processing friendly comprises that melting heat is low makes that solid binder melts fast in production atmosphere, use the low binding agent that makes of viscosity by applying the nozzle required minimum pressure that flows, and when cooling fast setting so that possibility seepage (bleedthrough) minimize to undesirable adhesive flow of working roll.Hereinafter will describe each in these binder performances in detail.
Fast fusing is useful, and this is owing to be one of factor of noting of people of needing those operations to process with adhesive tape required time under the condition easy to use.Short fusing time means the less attention that only needs the operator after replenishing the adhesive melts groove that uses up.
Just as noted above, when using binding agent to connect material when the assembling absorbent device, the low viscosity under the processing conditions is very important for making binding agent by applying the mobile required minimum pressure of nozzle.As those of ordinary skills recognized, under high serviceability temperature, apply binding agent and can realize the low viscosity of using.But, realize that this class measure of low use viscosity has caused other problems.For example, in the time of may needing binding agent is heated to above binding agent and becomes the friendly shape of material under the required temperature.Another problem that causes owing to high temperature is " storage period (pot life) ".Because hotmelt is the compositions that comprises organic material, if material at high temperature keeps the long time, then this material may begin degraded." storage period " be the performance at material become unacceptable before (viscosity loss that causes as, taste, color and owing to molecular weight degradation) may remain on the time under the molten state.In addition, if may realize gratifying viscosity, then storage period can be prolonged in lower applying under the temperature.
The processing health also is important when producing absorbent device.The set time of binding agent is important in this case, if this is that then fluid adhesive may pass through the roller of material (as nonwoven closing in parts) infiltration and pollution lower floor because the set time is oversize.In case the bonded agent material of roller pollutes, any width of cloth that then roller carried may be fixed on the roller and wrap up roller, causes width of cloth fracture.
The adhesive material performance
The qualitative standard of above-mentioned material friendly and processing friendly helps to identify several important material property of binding agent of the present invention.Particularly:
1) viscosity/temperature relationship (viscosity-hot property) limit apply temperature and
2) temperature of binding agent is brought up to the easy degree that the required energy of temperature limits fusing that applies.
Hereinafter will go through each in these character.
Consider that following factors can limit viscosity-hot property:
In order to become the material friendly, then adhesive material should have about 350 (177 ℃) or the lower temperature that applies according to the present invention.Otherwise, on some useful web materials, may begin to occur visible defects.Preferably, apply temperature less than about 335 °F (162 ℃).
According to the present invention, apparent viscosity is less than or equal to about 20 under about 177 ℃ temperature, 000 centipoise, preferably be less than or equal to about 16,000 centipoises, be more preferably less than or the material that equals about 12,000 centipoises will have gratifying by applying the flowability of nozzle.Can use from Brookfield Engineering Laboratories according to ASTM standard technique D3236-88, Inc., Stoughton, the Brookfield Model DVI of Massachusetts or model DVII and No. 27 spindle sizes can be measured apparent viscosity.
Binding agent should have fast setting to guarantee that the infiltration by the porous width of cloth is to make us unacceptably low.
The apparent density of following table binding agent more of the present invention (block copolymer of having bought with HL-1719) and polybutylene-based binding agent (available from the market and can be, Milwaukee, Wisconsin has bought) from Ato Findley with H9268.
Table I
The relation of apparent density and temperature
| Temperature (°F) | Binding agent of the present invention (centipoise) | Polybutylene-based binding agent (centipoise) |
| 350 | ?11,000 | ?6,300 |
| 325 | ?18,900 | ?10,000 |
| 300 | ?36,400 | ?15,000 |
| 275 | ?80,000 | ?23,000 |
| 250 | ?198,000 | ?41,000 |
As can be seen from the above table, in measured temperature range, binding agent of the present invention has higher apparent viscosity than polybutene binding agent.Even so, binding agent of the present invention remain the processing friendly with the material friendly.
The lower melting heat that it is believed that binding agent of the present invention means the set time may make us unacceptably short, still can keep ideal viscosity/temperature relationship mentioned above simultaneously.Just as is known, at mobile time and the more flowing time of the more low viscous fluid needs of more full-bodied fluid ratio of needing on specific distance of fluid under the given pressure reduction.Also as known to, from the heat passage thermal capacitance and the crystallization heat that depends on the temperature difference of material and surrounding, the material area that is exposed to environment, material of material.
Binding agent of the present invention has uncommon low fusing/crystallization heat, and this makes under identical cooling condition its temperature descend more quickly than the binding agent of prior art.Be not wishing to be bound by theory, the lower combination of loss faster that applies temperature and temperature that it is believed that binding agent of the present invention means binding agent of the present invention and solidifies in the shorter time.
The applicant thinks that the difference that adds heat distribution (heating profile) can explain by the melting heat of various adhesive compositions.Term used herein " melting heat " is the required energy of crystal melting of material.Melting heat can use hereinafter and measure in the differential scanning calorimetric technology described in the Test Methods section.Make binding agent of the present invention in order to be suitable for, the melting heat of adhesive composition should be less than about 5 Jiao/grams and preferred molten heat less than about 2 Jiao/grams.

Close up and assemble and fix
Just as noted above, oil-resisting adhesive material is suitable for to be done arbitrary or all flap conjunctions 88, elasticity conjunction 90, nearly fixture 92 or interval Flexible Connector 94.A kind of method that applies as the binding agent of the present invention that forms the interval Flexible Connector 94 that stops closing in 62 hereinafter is discussed.One of skill in the art will recognize that adhesive material of the present invention is used similar approach on other parts of diaper 20.
Can be clear that from Fig. 3 elastic component 76 is included in the groove at interval, this groove is to form from folding on one's body when the end that stops closing in part 63, and elastic component 76 is fixed in the hole by interval Flexible Connector 94 at interval.The distal edge 66 that stops closing in separates away from health face 40 by the elasticity collecting action of interval elastic component 76.For: 1) form this groove, 2) fixing elastic partition member 76 and 3) collecting action is provided, have been found that the following step is fit to.
● at first, provide elastic component 76 at interval.But being suitable for, the material of any elastic shrinkage makes elastic component 76 at interval.In United States Patent (USP) 4,695,278 mentioned above, concrete material has been described also.
● secondly, provide suitable interval Flexible Connector 94.Just as noted above, adhesive composition of the present invention is particularly preferred.
● the 3rd, use method well known in the art that interval elastic component 76 is linked together with interval Flexible Connector 94.Suitable method includes but not limited to: interval Flexible Connector 94 narrow slits extruding (slot extrusion) are sprayed onto on the elastic component 76 of interval to interval elastic component 76 and with interval Flexible Connector 94.Particularly preferred be to use spiral pattern well known in the art at interval Flexible Connector 94 be sprayed onto at interval on the elastic component 76, thereby the width of spiral should make with interval Flexible Connector 94 be carried to elastic component 76 at interval around so that all surface of Flexible Connector 94 contact interval elastic components 76 at interval.That is, elastic component 76 is spaced apart Flexible Connector 94 parcels at interval.
● the 4th, provide to be applicable to that formation stops the web material of closing in part 63.This class material is described as and is applicable to that formation stops closing in 62 in United States Patent (USP) 4,695,278 mentioned above.
● the 5th, by a part is stopped closing in part 63 be folded in the interval elastic component 76 that is wrapped around and use method well known in the art will stop that closing in part 63 and the interval elastic component 76 that is wrapped are combined and the elastic partition member 76 that is wrapped is connected to stops on the closing in part 63 (formation stop close up 62).Use stops closing in closure member 96, as the heat and the combination of pressure, be known as usually crimping, adhesive members or miscellaneous part known in this field with the longitudinal edge of this part elastic partition member be connected to the interval elastic component+remainder on.
E.
Skin care compositions is applied to closing in (or on other width of cloth)
When preparation treated closing in product of the present invention, preferably skin care compositions is applied on the health face (that is wearer-contacting surface) of closing in.But because disclosed some skin care compositions of the present invention can be by this paper disclosed some infiltration of closing in materials or migrations, skin care compositions also can be applied on the medicated clothing face of closing in so that the skin care compositions of effective dose is assigned on the health face.In fact, in some cases, this may be to obtain all preferred versions of the beneficial effect of the closing in (that is, both sides are all processed) of processing, although only be applied on the surface.
Can use and distribute in the multiple applying method of lubriation material with fusing or liquid consistency any that skin care compositions is applied in the closing in.Suitable applying method comprises coating (as intaglio plate coating or narrow slit coating), sprays, printing (aniline printing), extruding or these or other apply technology combination (as, skin care compositions is sprayed onto on the surface of rotation, as felt wrapped roll, the surface of this rotation is transferred to skin care compositions on the surface of diaper closing in by the contact coating then).If desired, skin care compositions can be applied on the both sides of closing in.
The mode that skin care compositions is applied in the closing in should make closing in not by the skin care compositions supersaturation.If handle closing in excessive skin care compositions, then for example enter the probability of inside of articles for use to undesirable position of articles for use bigger for migration of skin care composition, may destruction be arranged to the absorbability of the absorbent article core of lower floor at described undesirable position skin care compositions.In addition, for obtaining the benefit of treatment and/or protectiveness skin care compositions, closing in does not need saturated.
The minimum that will be applied to the skin care compositions in the closing in is effectively to reduce erythema, diaper rash, the red marking (red marking), skin irritation or other unfavorable skins.(compositions can also effectively reduce BM and adhere on the wearer's skin.) certainly, the effective dose of skin care compositions depends on used concrete skin care compositions to a great extent.Because lubricant is fixed on the health face of closing in basically, so only need less skin care compositions just can give required skin protection beneficial effect.The skin care compositions of described quite low consumption is enough to give the close up required treatment and/or the beneficial effect of protectiveness skin care compositions.
Skin care compositions evenly and equably can be applied to close up or its part arbitrary or two surfaces on.Also the form of skin care compositions with pattern (that is, bar, box, point, spiral etc.) can be applied.Preferably, skin care compositions will contact maximum region alignment with the wearer in use with closing in.Most preferably, described in embodiment hereinafter, skin care compositions is applied to the discrete locations place of closing in strip, for example usually 1.4 inches wide (diaper is horizontal, and the distal edge that make to close up is capped) and 11.75 inches long (diaper is vertical) sticking patch (patch) are distributed in the crotch portion of health face of closing in.
Also skin care compositions can be applied to unevenly on any or two surfaces of closing in." inhomogeneous " refers to the consumption of skin care compositions, the pattern of distribution etc. and can change on the surface of closing up.For example, the skin care compositions that some part on the treated surface of closing in can have more or less amount comprises on it surface portion without any compositions.
Skin care compositions can be applied in the closing in any moment of assembly process or form on the width of cloth of part closing in.For example, can finished product packing before, skin care compositions is applied in the closing in of finished product.Also can be before closing in or the width of cloth and other material combination form finished product, with skin care compositions be applied to close up or the width of cloth on, perhaps with the miscellaneous part combination of articles for use before the repacking position or apply as pretreated raw material.
Usually the skin care compositions with molten condition is applied in the closing in.Because skin care compositions is in fusion under the temperature of ambient temperature, therefore with the form of the coating of heating skin care compositions is applied in the closing in usually.Usually, before being applied in the closing in, skin care compositions being heated to temperature range being about 35-100 ℃, preferably about 40-90 ℃.In case fused compositions is applied in the closing in, makes its cooling and solidify to be distributed in close up lip-deep cured coating or thin film with formation.Preferably, the design applying method is with the cooling that helps compositions/fixing.
When being applied to skin care compositions of the present invention in the closing in, preferably adopt methods such as narrow slit coating, extrusion coated, intaglio plate coating, spraying.Fig. 5 shows a kind of preferable methods, and this method is included in repacking operating period and skin care compositions is contacted narrow slit continuously or discontinuously is applied to diaper and stops in the closing in.Referring to Fig. 5, conveyer belt 1 runs on slewing rollers 3 and 4 and becomes the conveyer belt 2 that returns along the direction shown in the arrow.Conveyer belt 1 carrying is not applied with the diaper 5 contact narrow slit coating stations 6 of skin lotion, stops that herein closing in part 7 is coated with (as 65 ℃) skin care compositions heat, fusing.After leaving narrow slit coating station 6, diaper 5 becomes and has the treated diaper that stops closing in 8.Transferring to the amount that stops the skin care compositions on the closing in part 7 controlled by following factors: (1) applies the amount (rate) of the skin care compositions of fusing from contact narrow slit coating station 6; And/or (2) conveyer belt 1 is in the speed of 6 times operations of narrow slit coating station; And/or the position of (3) contact narrow slit coating station.(if desired, coating station can be positioned to be coated with on feasible closing in of the part that stops closing in part 7 and top flat 38 and the top flat and be distributed with skin care compositions.)
